污水汽提装置控制系统及安全联锁设计

石油化工企业含硫污水中硫化物和氨氮含量较高,若不经过处理而直接排入污水处理场将导致严重的环境污染,建设一套高标准、可靠运行并且节能环保的污水汽提装置势在必行。从安全环保、精确检测及控制、高度自动化水平的角度出发,研究和讨论安全联锁仪表系统、过程检测及控制系统、可燃气体/有毒气体检测系统、火灾报警系统、视频监控系统、无线检测系统、自动装车控制系统在污水汽提装置中的设计与应用。

In petrochemical enterprises,the content of hydrogen sulfide and ammonia nitrogen in sour water is higher,if it is not treated and discharged directly to sewage treatment plant,which will lead to serious environmental pollution.it is imperative to build a set of high standard,reliable operation,and energy saying and environmental protection sour water stripping unit.this article embarks from the safe environment protection,the accurate examination and the control,the highly automated level angel,the design and application of safety interlock instrument system,process detection and control system,flammable gas/toxic gas detection and alarm system,wireless detection system,automatic loading control system,in sewage stripping unit are studied and discussed.
